I'm seeing something similar to this, using the 2.6.10 kernel with Fedora Core 3
patches. It's less frequent than in 2.6.9, but it still isn't fixed.

I can trigger it pretty consistently by copying an 8 gigabyte file (containing
/dev/random output) using an NFS client, from one NFS export to another, both on
the same XFS filesystem. The filesystem resides on a software RAID-5 device. The
kernel panic usually happens within 3 attempts.

The crash does not happen if I perform the same operation (client file copy -
same file - between NFS exports) on an ext3 filesystem.

I'll see if I can get a trace, but I'm pessimistic. The last 60 lines shown in
my local console are meaningless (seems like a crash in crash handler), NIC
driver does not support netconsole, no SCSI devices for raw core dump support,
